The build worked on build machines running macOS 10.7–13 but we saw the same error on the 10.6 build machines:

​https://build.macports.org/builders/ports-10.6_x86_64-builder/builds/207893/steps/install-port/logs/stdio

Searching for dpstrf I found it is part of BLAS. Maybe the problem is that the build uses BLAS_LIBS="-L/opt/local/lib -lvecLibFort" and maybe libvecLibFort doesn't have this symbol on 10.6 and earlier.

This sounds very likely.

I will see if this will build against OpenBLAS instead. Thank you for pointing out.

This returns me to a need to fix our broken linearalgebra PG. Currently it forces +accelerate on older platforms, and my last attempt to sort this out did not quite work out.
